Patent DE-3011324-A1 (DE)
Title: Error detection for digital transmission systems - uses command and test words inserted as scrambled text. into frame structure
Inventor: POSPISCHIL REGINHARD DR ING
IPC: H04B17/40
Filed: 1980-03-24
Abstract: The circuitry is used for producing an error detection code which can be used with intermediately regenerated scrambled 565Mbit/AMI/s/digital transmission lines. The frame alignment word (RKW) is transmitted and the command (KT) and test words (PT) are inserted in the frame structure. The tests are intended for out-of-service checks using loop backs from the intermediate regenerators. Four tributaries (1,2,3,4) are connected into changeover switches (6,7,8,9) prior to being connected through exclusive-OR gates (10,11,12,13) into the 565Mbit/s Multiplexer (MUX). The changeover switches (6,7,8,9) are provided with a control input(St) for changeover to receive the scrambled command words (at K1,K2) on the input of each tributary(at 6,7,8,9). The test word are clocked, using sync clock sources (TL1,2,3,4), from the pseudo random scramble text generator (PN) into the exclusive-OR gates (10,11,12,13) for mod-2 addition and transmission through the multiplexer (MUX). The command words are related in length to the number of tributaries in the system and the spectral content is related to attenuation and the Nyquist characteristics of the line.

Title: Oil vapour seal for scanning motor bearing - blocks vapour escape with helical grooves on motor shaft in end shields
Inventor: TAKAHASHI TSUNEHIKO
IPC: F16C33/80
Filed: 1980-04-23
Abstract: The elimination of oil vapour escape from the bearing of a fast revolving motor carrying the scanning mirror is achieved by grooves or projections on the surface of the rotating part. These surface irregularities give rise to air streams along the wall of the rotating part to prevent diffusion of oil vapour. The scanning mirror (10) is driven by motor (50) and grooves (53) follow a helical line on part of motor shaft (51). This blocks exit of oil vapour from ball bearings (31) and out of gaps (54).
Patent DE-3017354-A1 (DE)
Title: Cap for aerosol or similar spray container - has thin holding ribs to engage below container rim thus avoiding uneven cooling after demoulding
Inventor: DIEBEL HERMANN
IPC: B65D83/14
Filed: 1980-05-07
Abstract: An injection moulded, plastics closure cap for a container, esp. a spray container, is designed as a push-on, pull-off cap held in position on the container by projections which engage beneath the container rim. These projections are formed as a large number of fine ribs arranged alongside one another and pref. parallel to the direction in which the cap is removed from its mould, i.e. the same direction as that in which it is pulled off the container rim. More uniform cooling of the entire cap after removal from the mould, gives a better quality of structure and avoids collapse or shrinkage points normally found near the thick ribs or projections used for holding caps onto the vessels. Thus production cycles can be speeded up.

Title: Bellows gas meter with small movement resistance - has two crank arm halves forced apart by expanding spring
Inventor: BERTKE HEINRICH
IPC: G01F3/22
Filed: 1980-06-25
Abstract: A bellows gas meter in which two chambers are each divided into two measurement volumes by membranes, has a spring element practically unloaded over the greater part of its stroke and loaded only in the region of the dead point. This results in a relatively small resistance to be overcome without degrading the transfer of motion via the rods. This is achieved by making each arm of the crank (44) of two halves (46,48) able to move relative to each other in the longitudinal direction. The two halves of the crank arm are forced apart by a spring element (50). One half has guide grooves (52,54) on its parallel sides in which the other half moves longitudinally. The spring element is of the expanding type.

Title: Synchronous demodulator using four-pole network - has frequency demodulator receiving square of input and reducing noise of e.g. FM signal
Inventor: HOFFMANN MICHAEL DIPL PHYS
IPC: H03D3/00
Filed: 1980-08-29
Abstract: The four pole network is followed by a frequency demodulator (MD). The network receives the signal (v(t)) to be demodulated as its input and supplies an output to the frequency demodulator (FMD) which is the square or a higher power of the input, or which is the sum of given powers of the input. The 4-pole network pref. comprises a synchronous envelope curse demodulator (SHD) and a multiplier (M), both of which receive the input signal (V(E)). The output (VH(t)) of the envelope curve demodulator (SHD) proportional to the mathematical envelope of the input is fed to the second input of the multiplier (M). The output of the latter is proportional to the square of the envelope curve of the input signal (V(t)) and the demodulator receiving this is tuned to the centre frequency of the input signal (V(t)). The demodulator reduces noise due to signal spikes.

Title: Tooth crown internal cone production process - involves measuring upright quadrant faces of teeth after determination of common insertion direction
Inventor: PFLAUM RAINER
IPC: A61C5/77
Filed: 1980-09-02
Abstract: The dental process produces the internal cones of tooth crowns, the model being first placed on the adjusting table of a parallelometer. A common ideal insertion direction is then determined by passing a parallel pin around the quadrant faces of all tooth uprights. Wax is then applied to the uprights. The wax is modelled by shaving, while continuously checking the taper of the quadrant faces, into blanks which are removed from the uprights, metallic internal cones being cast onto them. The cones are fitted onto the uprights and machined on the quadrant surfaces by milling tools. After determination of the common insertion direction, the quadrant faces of the uprights are measured to determine the best angle for all, giving a fixed cone angle for these faces. Wax is applied to the uprights and modelled at an angle between the insertion direction and half the fixed cone angle.
